My first observation was in the town/village where I grew up (my family is not closely related to race). I noticed that almost everyone in the village is a businessman-a businessman in the whole town-who either opens a small shop every day or goes to a big city nearby to open a bigger shop. They think that all those who are employed are slaves, and their children have learned bookkeeping in primary school (not in my school). I used to think, how can a group of people buy and sell like this? Shouldn't someone give birth, too?
In fact, few people outside the village use groundwater to grow vegetables, but these people are considered unqualified. Don't mix with them, and don't marry them. The land in the village is desert, which must be the reason. But now I think of a broader reason-evolution and the struggle on agricultural land must have played a role, dividing people into businessmen and doers who use muscles. The third group, including me, seems to be not interested in anything that has nothing to do with intelligence. This must be the priest of the ancient temple-my grandfather is like this, which is purely coincidental. When he died, his oldest child was only a teenager, so it didn't affect me. As we continue, this idea will prove to be useful.
Later, I learned another interesting fact-that is, all Homo sapiens originated near Ethiopia in East Africa and then migrated to the north-it is said that they passed through Sudan and Egypt and then migrated to the north and east. The route of the rest of the world is similar to Wikipedia, the origin of modern human beings in Africa, which was recently drawn on the left.
Please note; These routes completely avoid the Arabian Peninsula (left). This seems unconvincing to me-because early humans managed to cross many rivers and oceans on the same map, but failed to walk a distance to the Arabian Peninsula. I think this is the intentional negligence of some people who don't like the consequences. In Iraq, Syria and Yemen, the same armed forces seem to be destroying historical sites in the region. During the Iraq war, the ruins of Babylon were used as the action center of the invading army, not to mention looting museums! !
After that, I saw a more logical and convincing migration scene, the so-called coastal route theory-see the figure below. See quoting the link above; "About 50,000-70,000 years ago, a group of carriers of mitochondrial haplogroup L3 migrated from East Africa to the Near East ... The population of Africa was only 2,000-5,000 ... A group of people crossed the Red Sea ... Those who crossed the Red Sea bypassed the Arabian and Persian plateaus along the coastal route and arrived in India". See also the following road map; Early human migration-Wikipedia; "The migration of early modern humans was based on the distribution of mitochondrial haplogroup." Semite-Wikipedia, the African origin of modern humans-Wikipedia. These will also help the answer.
